Advanced Reactors

The Canadian Nuclear Safety Commission has announced its approval for Ontario Power Generation to construct a General Electric Hitachi BWRX-300 small modular reactor at its Darlington site in Clarington, Ontario.

Dow and X-energy announced today that they have submitted a construction permit application to the Nuclear Regulatory Commission for a proposed advanced nuclear project in Seadrift, Texas. The project could begin construction later this decade, but only if Dow confirms “the ability to deliver the project while achieving its financial return targets.”

In a strongly worded opinion piece published by Power Magazine on March 24, Tennessee Sens. Marsha Blackburn and Bill Hagerty call for new leadership at the Tennessee Valley Authority to jumpstart its small modular reactor program.

The GOP lawmakers are looking to President Donald Trump and Energy Secretary Chris Wright to overhaul TVA’s board of directors to drive America’s role in the nuclear renaissance. TVA is the first and only U.S. energy company to obtain an early site permit for a small modular reactor, but the utility has not progressed on physical deployment of a unit since the permit was awarded in 2019.

Prodigy Clean Energy and Lloyd’s Register have announced a collaboration to support the deployment of Prodigy’s “transportable nuclear power plants” (TNPPs) in Canada by 2030. Prodigy’s goal is to build marine-based nuclear power plants that are compatible with different end uses and reactor suppliers. What the plants would have in common is offshore siting close to an end user, which could include offshore oil and gas platforms, commercial seaports, mining operations, remote communities, and desalination plants.

New commentary on the Nuclear Regulatory Commission’s proposed 10 CFR Part 53 licensing recommendations for advanced reactors argues that more work is needed to make the framework practical.

TerraPower has continued to make aggressive progress in several areas for its Natrium Reactor Demonstration Project since the beginning of the year. Natrium is an advanced 345-MWe reactor that has liquid sodium as a coolant, improved fuel utilization, enhanced safety features, and an integrated energy storage system, allowing for a brief power output boost to 500 MWe if needed for grid resiliency. The company broke ground for its first Natrium plant in 2024 near a retiring coal facility in Kemmerer, Wyo.

Small modular reactors, as the name implies, are meant to be small, each one generating less than 300 megawatts of electricity. They are modular in the sense that the units belonging to the same design look alike, and their parts can be manufactured in factories at various locations and then shipped to a central location for assembly.

Penn State and Westinghouse Electric Company are working together to site a new research reactor on Penn State’s University Park, Pa., campus: Westinghouse’s eVinci, a HALEU TRISO-fueled sodium heat-pipe reactor. Penn State has announced that it submitted a letter of intent to host and operate an eVinci reactor to the Nuclear Regulatory Commission on February 28 and plans to engage with the NRC on specific siting decisions. Penn State already boasts the Breazeale reactor, which began operating in 1955 as the first licensed research reactor at a university in the United States. At 70, the Breazeale reactor is still in operation.

Leaders from Holtec International and Hyundai Engineering & Construction gathered at the Palisades site in western Michigan today to announce an “expanded cooperation agreement” to build a 10-GW fleet of Holtec-designed SMR-300s in North America. That fleet’s first builds would be at Palisades, where Holtec is now focused on restarting the site’s shuttered 777-MWe pressurized water reactor by the end of this year. Under the “Mission 2030” plan launched today, Holtec would then build a pair of SMR-300 PWRs at the Palisades site—targeting operation in 2030.

U.K.-based Core Power has announced that it intends to develop a maritime civil nuclear program anchored in the United States with the goal of bringing floating nuclear power to market by the mid-2030s. The program, called Liberty, is to encompass the modular construction of advanced reactor technology and create the regulatory and supply chain frameworks needed to begin the mass production of floating nuclear power plants (FNPPs) on a global scale.

The International Energy Agency has published a new report examining opportunities for the nuclear power industry to address concerns related to energy security and climate change. The Path to a New Era for Nuclear Energy explores areas of policy, innovation, construction, and financing with an emphasis on investment-related issues regarding small modular reactors.

The IEA report describes encouraging developments taking place in the nuclear energy industry, such as increasing investment, technology advances, and supportive policies in many countries. But it also notes that certain key challenges need to be overcome if nuclear energy is to meet the needs of rising electricity demand, including demands from artificial intelligence and data centers. In addition to examining the present global status of nuclear power, the report evaluates the long-term outlook, quantifying expected capacity and investment through 2050.

Texas A&M chancellor John Sharp has announced that the university could soon become a home to small modular reactors from four advanced nuclear companies: Kairos Power, Natura Resources, Terrestrial Energy, and Aalo Atomics.

To better educate customers and stakeholders on its technology, NANO Nuclear Energy has opened a new demonstration facility in Westchester County, N.Y., that offers an up-close look at nonnuclear parts and components of the four microreactors the company has in development.

A team of innovative companies has plans to bring floating nuclear power plants to U.S. ports.

Core Power, a maritime and nuclear technology company, announced in January a new partnership in with naval architecture company Glosten. The pair is working on a design for a floating nuclear power plant (FNPP) that could generate up to 175 gigawatt-hours of clean electricity annually and provide clean power to ships, equipment, and port vehicles, Offshore Energy reported.

A 1,300-acre site left undeveloped on the shores of Lake Ontario four decades ago could see new life as the home to a large nuclear facility.

The Department of Energy has announced a competitive funding opportunity of up to $13 million to help first movers defray the licensing costs of bringing advanced nuclear reactors to market.

“SMRs present a viable opportunity for Indiana to transition to a cleaner, resilient, and diversified energy future. Successful deployment of SMR technology requires a careful balance of economic, regulatory and social considerations along with development of the technology.” Those are among the conclusions of a comprehensive study conducted on small modular reactors primarily by researchers at Purdue University and funded by the Indiana Office of Energy Development.

Advanced nuclear company Oklo and data center developer Switch closed out 2024 by announcing a new partnership to deploy 12 GW of advanced nuclear power under a master power agreement.

TerraPower announced this week that it has awarded the major manufacturing contracts for its Natrium plant reactor enclosure system.

These vendor awards help advance deployment and commercialization of what the company is calling “America’s first advanced reactor,” according to TerraPower’s press release. The news is also a major milestone in establishing the advanced nuclear supply chain, the company added.

BWXT Canada, a subsidiary of BWX Technologies, is partnering with Westinghouse Electric Company to build new nuclear projects in Canada and globally.
